Abstract

In order to improve the overall performance, the combined cooling, heating and power system is analyzed with power generation unit as the core. The system combines renewable energy which include ground source heat pumps, photovoltaics and solar thermal technologies. The efficiency of the system is focused on research. Based on device complementary characteristics, the way is proposed by optimizing a number of control parameters. The parameters include the start factors of the ground source heat pump in cooling and heating mode and the power generation unit. Combining the start factors of controlling multiple devices with following electric load operation mode and the following electric load operation mode are comparative analysis. The black hole algorithm is used to optimize the system. The research results show that the system has better performance with multiple start factors compared with the traditional model. Compared with the reference system, the performance indicators of the renewable energy system have been greatly improved, especially using the start factor mode operation （the annual energy saving rate reaches 36.03%; the annual carbon dioxide emission reduction rate reached 53.24%; the total annual cost reduction rate reached 36.85%; the annual comprehensive performance reached 42.04%）.
